Which of the following part of a flower is not a reproductive organ?

Correct option is D

The correct answer is (d) Sepal
Explanation:
. Sepal is a part of the calyx and is a non-reproductive (accessory) organ of the flower.
. Its main function is to protect the flower bud during the early stages of development.
. Stigma and style are parts of the pistil (female reproductive organ).
. Anther is a part of the stamen (male reproductive organ) and produces pollen grains.
. Thus, sepal does not take part in reproduction.
Information Booster:
. A typical flower has four whorls: calyx, corolla, androecium and gynoecium.
. Androecium and gynoecium are the reproductive whorls of a flower.
. A complete flower contains all four whorls.
Additional Knowledge:
Stigma (Option a)
. It is the receptive, sticky part of the pistil.
. Pollen grains land and germinate on the stigma.
Style (Option b)
. It is a slender stalk connecting stigma to ovary.
. It provides a passage for pollen tube growth.
Anther (Option c)
. It is the pollen-producing part of the stamen.
. It contains pollen sacs filled with pollen grains.
